Percentile CI. With above notation, percentile CI is: (θ (1 − α)/2, θ 1 − (1 − α)/2) WebThis implies that with a probability 1 1e , one of the observation in the bootstrap sample will select the minimum value of the original sample M n. Namely, P(M n= M ) = 1 e 1: Thus, M nhas a huge probability mass at the value M , meaning that the distribution of M n will not be close to an exponential distribution. 5.2 Parametric Bootstrap
